These 5 viscometers can be used for viscosity testing of cemented carbide mixture slurry [instrument suggestion]

This article is a Rotational Viscometer solution chosen by a hard new material user to test the viscosity of cemented carbide mixtures. The viscosity of the cemented carbide mixture is one of its quality indicators. The quality of the mixture will directly affect the internal material and appearance quality of the cemented carbide. Therefore, manufacturers need to carry out viscosity testing in the production process.

The specific parameter requirements are: to test the cemented carbide mixture slurry, the viscosity range is 100-2000cp, and the rotational speed is required to be 100-2000 mPa/s.

According to the needs of users, the technical engineers of NBCHAO Mall suggest three different grades of rotational viscosity instruments, medium, high-low, for users to compare and choose by themselves. As shown in the following table:
